LEAF-SPRING- OILER.

Application filed November 23, 1921, Serial Ito/517,264. Renewed May 22, 1924.

To all whomjt may concern:

Be it known that we, HIRAM H. SHELTERS and HARLEY A. BASHAW, citizens of the United States of America, and residents of Burlington, county of Chittenden, and State of Vermont, have invented certain new and useful Improvements in Leaf-Spring Oilers, of which the following is a full and clearv specification.

The object of this invention is to provide a simple and inexpensive flexible envelope for oiling leaf-springs, the device being oilproof, dirt-proof and water-proof, as more fully hereinafter set forth.

Fig. 1 is a perspective. view. of a part of a leaf spring showing our device applied thereto;

Fig. 2 is a transverse sectional view thereof; I Fig. 3 is a perspective view of the cover unfolded. I

In the drawing, 5 designates the outer fabric of the envelope which may be leather, leatherette, oil-cloth or any fabric which is waterproof. This fabric is provided along one longitudinal edge with a hem which encloses a metal rod 6, and along its two end edges it is hemmed for the purpose of receiving in each hem a draw-string 7. Affixed to the inner face of the outer fabric 5 are two paper sheets, one, 8, next to the fabricone longitudinal edge, the sheet 8 is provided with a flap 10, the longitudinal and end edges of this flap being hemmed and stitched for the purpose of preventing tearing and also for the purpose of receiving a series of headed metallic fasteners 11.

The other,-oil-proof, sheet 9 is also provided with a flap 12 which is considerably wider than the flap 10, bein wide enough to project beyond the wired e ge of the main fabric 5 when opened out flat. Attached to the face of this flap by lines of stitching 13 is a felt pad 14: consisting of one or more thiclmesses of ordinary oil-absorbing felted material. 7

The envelope constructed as above described is folded about the leaves composing the spring, the pad being wide enough to extend across the top (or the bottom) surface of the spring and along the edges theredust and .dirt,

pressed down thereon so as to cause the fastening-pins to puncture all the thick- "nesses; then the wired edge of the main fab ric is finally folded over upon the fastening devices and pressed down thereon so as to be punctured thereby; then the projecting ends of the, fastening devices are bent down in the manner of paper fasteners to secure the parts in folded relation. Then, as a final securing means, thedraw-strings are-drawn taut'and tied, so as to thereby tightly close the ends of the envelope against dirt and dust. The wire 6 prevents the outer edge of the fabric 5 from folding or puckering, thus maintaining a tight dust-proof joint along the entire longitudinal edge of the envelope.

It will be observed that the device may be readily removed by straightening the pointed ends of the fasteners so as to permit the various fabrics to be pulled off the points of the fasteners; and then the device may be-reapplied in the same manner after a fresh supply of oil is given to the p It will be observed that our device is simple and inexpensive, easily applied and re-' moved, and practically dustand waterproof. It will be observed also that the manner in which the oil-pad is unfolded ensures against any material evaporation or leakage of the oil and that a thorough and uniform lubrication of the leaves of the spring will be maintained so long as the oilsupply lasts.

It will be observed also that the unsightliness due to leakage of oil and deposit of which is common to the devices now'on the market, is entirely avoided and that, therefore, our device will at all times have a neat and clean appearance.

- Another feature of importance is that a dealer by carrying in stock a reasonable number-of sizes may fit the springs of any one of the stock cars now on the market, thereby rendering it unnecessary to carry a large supply 'of sets for different cars; this is rendered possible by reason of the adjustability of the fastening arrangement and by providing for taking care of any surplus Width through the medium of the wide outer flap. e

The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically described, what is claimed as new is:

1. An oiling envelope for springs consisting of a main water-proof fabric having a drawstring attached to each end and having also a stiffening member attached to one of its longitudinal edges, an oil-pad .attached to the inner face of said fabric, and a flap attached to the inner face thereof and carrying fastening devices adapted to engage the stiffened edge of said main fabric, for the purpose set forth.

2. An envelope for leaf-springs embodying a waterproof main fabric, an oil-carrying pad attached to the inner face thereof, a flap also attached to the inner face of the inner fabric and carrying fastening devices,

one edge of said main fabric being provided with a hem which encloses a stiffening rod, for the purposeset forth.

3. An oiling envelope for springs consisting of a main fabric, a waterproof fabric afiixed to the inner face thereof and having a flap formed along one edge, said flap being provided with a series of outwardly-directed fastening devices adapted to pass through the main fabric along one edge thereof, an oil-proof sheet also affixed to the inner face cf'said main fabric and having a free flap along one edge, and an oil-absorbing pad carried by this latter flap.

4:. A spring oiling appliance consisting of a flexible envelope, a wire extending along one edge thereof, an oiling pad fastened to the inner face of the envelope, and means for fastening the envelope upon the spring with said wired edge lying on and pressed against the outside of the opposite edge of the envelope, to thereby insure a tight joint throughout the length of the envelope.

In testimony whereof we hereunto aflix our signatures this 18th day of November, 1921.
